7mgte to 7mge conversion help

[wayzhack]

Yeah you read that right. Well actually I dont have a 7mgte engine, but Im trying to drop a 7mge engine, tranny, and ecu into a 1988 Toyota Supra Turbo shell.

Anyway, from what Ive read on here, I can pretty much bolt on the new tranny and engine, but what I need to know is if there is anything else that I will need for the conversion? My main question is: Will I be able to use my turbo harness for the n/a engine, or will I need to go buy a 7mge engine harness?

Once again the car is set up for a 7mgte turbo engine and 5spd transmission, but I am swapping in 7mge non turbo engine and auto transmission.

Yeah i know thats a totally hideous thing to do, but thats the cheapest option to get the car running while I save up for the 7mgte or 2jz...
